PNEUMAIlC-TIRE VALVE.

Application filed march s,

T 0 all whom it may concern:

Be it known that l, 'lnoivL-xs ll. ll'itss'ris, a citizen of the United States, reslding at Bristol, in the county of Bristol and State of Rhode Island, have invented a new and useful- Improvement in PueLnnatic-Tire Valves, of which the following is specification.

This invention has reference to an improvement in pneumatic tire valves and more particularly to an improvement in g i taming ring as shown in Fig. 2.

emergency valve nipples tor pneumatic tire valves.

in the use of pneumatic tire valves the. l small internal parts of the valve are l able to get out of order or broken, thereby ruining the utility of the valve. 'lhis generally requires a new valve which necessitates the removal of the tire from the wheel with con cap and having the screw-threaded hole. 15

sequent loss oi time.

The clnect of my invention is to provide an emergency valve nipple, whereby in case of accidents or failure of the tire valve to properly work, the'valvc nipple may be applied to the tire valve and the tire inflated in the usual way.

A further object of my invention is to con.- struct an emergency valve nipple so th; when in use the valve stem is provided wit 1 a ball check valve and a positive double closure valve.

My invention consists in the peculiar and 5 m ple lor rheumatic tire valves said valve I a doul' le the end of the valve stem.

will be more fully set iorth hereinafter and is first screwed onto the end 6 of the-valve claimed. 1

l merging into a larger screw-threaded hole 8 w 111 extends in from the end of the stem and forms an annular valve seat 9 in the valve stem at, as shown in Fig. 2. The air pipe connection is usually secured to the end of the stem 1, in the screw-tl'ireaded hole 8 in the end 01 the stem The emergency valve nipple 1) consists oi a cylindrical body member 0 in which is a ball check valve (6, a loose valve stem 5 and a re- The body member 0 1S constructed to have the internally-scrcw-threaded end 10 adapte to screw onto the end 6 of the valve stem at, the central cylindrical chamber 11 merging into the smaller ball valve chamber 12 having the valve seat 13, and the externally-screwthreaded end 1.4 adapted to receive a dust which entends into the ball valve chamber 12 and is adapted to receive the usual air pipe connection. The ball valve (1 has a loose lit in the valve chamber 12 and an air tight lit on the valve seat 13.

.he loose valve stem 6 has the enlarged circular head 16 in which are the two air dutes 17 1.7, a llat opposite valve end 18 adapted to have an air tight lit on the valve seat 9 in the valve stem a and is loosely held When in use the emergency valve nipple b stem (b into approximately the position, as shown in Fig. 2. The air pipe connection is now secured by screwing it into the screwthreaded .hole 15 in the nipple and the tire the emergency nipple T he ball valve d new acts on the valve seat 13 as a check valve to prevent the escape of air from the tire. When the tire is fully inllatcd the nipple b screwed down to its limit, thereby closing the flat valve end 1.8 of the loose valve stem 6 on the valve seat 9 in. the pneumatic tire valve stem a and closing the ball valve (1 onto the valve seat 13 in the nipple I), as shown in Fig. 3. A dust cap ina y now be screwed onto the screwthreaded end 14; ol" the nipple I). The emergency z nipple b is used ordinarily to temporarily repair the tire valvebut it may form a permanent part of the valve.

' ball valve, and a retaining f'ring adapted to valve -and a flat opposite 'in said chamber "having an enlarged Having thus described my invention, 1 claim as new and desire to secure by Letters Patent; l 1. An emergency valve nipple consistin of a cylindrical body having an interna screw-threaded end for securing the nipple to the screw-threaded end of a pneumatic tire valve, an internally and externally screw-threaded end for'anair pipe connection, and for a dust cap, a ball valve in the nipple, a loose valve stem supporting the hold the valve stem against downward movement in'i'ts operative position in the nipple. 2. An emergency valve nipple Z) consisting of a cylindrical body member 0 having the internally screw-threaded end 10, the central chamber 11, the valve chamber 12, the

seat '13, the externally screw-threaded end 14 in which is the screw-threaded hole 15, a ball valve d in the valve chamber 12, a loose valve stem e having the enlarged circular head 16 in which are the air ducts 17 17 l end 18, and a retaining I ring f having the notches 19 19 for removing or securing the ring in the bodv member a. I

3. A valve nipple composer having an interior chamber, a valve seat at the top end of the chamber, a ball valve to engage said valve seat, a loose valve stem ,l head under face of j said head of the loose valve stem, the top I of a body seat at the top end valve to engage said threads therein, a valve of said chamber, a ball seat, a loose valve stem in'said chamber, 40

.air ducts which extend therethrough, said all valve seating on and being su ported bysaid head, and a ring in said camber threaded into engagement with said screw threads thereof, said ring engaging the under fare of said head and thereby restricting the 5 downward movement of said loose valve stem.

5. A valve nipple composed of a body having an interior chamber, said chamber terminating at one end in a valve seat, a airi of independent valves in said chamber ch valves are free of permanent connection with each other and being arranged in super imposed relation whereby the upper valve receives support from the lower valve, the 0 uppervalve being for engagement onsaid valve seat, and the lower valve at ltslpwer end being for engagement wlth the valve seat in the valve stem of a )neumatic tire t 1e lower valve 5 valve, and means to engage to sustain the same against downward n1ove5 ment. I In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
